Abstract

In a global business context with continuous changes, the enterprises have to enhance their operational efficiency, to react more quickly, to ensure the flexibility of their business processes, and to build new collaboration pathways with external partners. To achieve this goal, they must use e-business methods, mechanisms and techniques while capitalizing on the potential of new information and communication technologies. In this context, we propose a standards, model and Web services-based approach for modeling and integrating agile enterprise business processes. The purpose is to benefit from Web services characteristics to enhance the processes design and realize their dynamic integration. The choice of focusing on Web services is essentially justified by their broad adoption by enterprises as well as their capability to warranty interoperability between both intra and inter-enterprises systems. Thereby, we propose in this chapter a metamodel for describing business processes, and discuss their dynamic integration by addressing the Web services discovery issue. On the one hand, the proposed metamodel is in line with the W3C Web services standards, namely, WSDL, SAWSDL and WS-Policy. It considers the use of BPMN standard to describe the behavioral aspect of business processes and completes their design using UML diagrams describing their functional, non-functional and semantic aspects. On other hand, our approach for integrating processes is in line with BPEL standard recommended to orchestrate Web services. To realize executable business processes, this approach recommends the use of semantic matching and selection mechanisms in order to produce agile systems.
